CENTER-BEARING.

amaze.

T 0 all whom it may concern:

Be it known that I, WILLIAM 11mm a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Center-Bearings, of which thefollowing is a description, reference being had to the accompanying drawings, which form a part of my specification.

My. invention relates to center-bearings for railway cars and the like, the object being to provide a construction that will not only be pr lly frictionless, but one in which the .par ill be held or locked into place andftli" "fprevent the different parts from readi etting out of proper position when 'th a mg is subjected to any undue or 'uriusu 1 rain by reason of unusual conditions.

A further object oprovide a bearing which. can readily bef'asseinbled and which is so constructed that 'th (irrect assembling of the parts will be insured,:thus preventing any possibility of the parts the following detailed description.

In the drawings: Figure"1 is a top plan view of my improved bearing, with a portion of the top member an intermediate or. driving member broken away. Fig. 2, is a cross-sectional view taken on the line 22 of Fig. 1. Fig. 3, is a top view of a portion of the intermediate member or driving-plate; and Fig. 4, is a bottom View of the same. Fig. 5, is a plan view of the separating member or ring; and Fig. 6 is a sectional 'view taken on the line 6-6'of Fig. 5. Fig. 1 is a diagrammatic view to hub w,

show the relation of the cone-bearing the bottom and intermediate members the bearing. Fig. 8 is a View similar Fig. 1. but showing'a modified construction; and Fig. 9 is across-sectional view taken on line 9-9 of Fig. 8. L

In the drawings, A and B are the outside or top and bottom members, respectively, which are providedavith the usual boltholcs so that they may be secured in place. The top member A. is preferably provided with (lOWllWHHilY-QXtOIldlfig annular flanges n and b. Member B is provided with the and the bearingsurface extends downwardly toward its periphery in order to have it conform to the style of bearing illustrated. A portion'of the upper part binding or inter. locking in any manner, as will appear from Specification of Letters Patent.

Application filed September 21, 1908. Serial No. 453,982.

provided with the preferably integrally v formed inwardly extending and horizontally disposed rim-portions or shoulder f, ata point diametrically opposite the shoulder or rim-portions d. Member B may be provided with the reinforcing rib g. In the construction shown, member B is provided on its upper surface with a circumferential groove at 72., into which the ringportion of the spacing and separating member C, shown in F 6 takes. This separating or spacing member C comprises the rin -portion 11, on which are mounted the ra ially extending spacing-portions j, which are spaced apart a sufiicient distance to receive between them' the bearing-rollers D. The rollers are preferably cone-shaped, and when desired may be provided at or near their outer ends with teeth is as illustrated in Figs. 1, 2 and 7. When this construction is used, the memberwith which the rollers contactis provided with an annular extending rackas for instance at the point 1, on member B with which the teeth on the rollers mesh.

Provided with a central opening to permitit to take about the main portion of the hub of member B, is an intermediate or driving-member E. The inner and outer peripheries of member E are provided with cut-away portions or notches as at m, n, which are formed at points to correspond with the rim-portions or shoulders (Z and f on the hub c and the portion or flange c of member B, which in the drawings are shown preferably diametrically opposite each other. These notches or cut-away portions m, n, are large enough to permit intern'iediate member 1*) to be placed below the shoulders or rim-portions on the hub and flange and in contact with the roller-bearings. In the preferred construction shown in Figs. 1 and 2, member E is, also provided with an annular rack 0, at or near its outer circumference which meshes with the teeth on the cone-bearings D, so that any movement of member E will be imparted to the rollerbearings. as is also the case when member B is moved. I

The bearing is assembled by first placing I extending spacing or separating member C in the roove h. in member B; the roller-bearings E are then placed into the sockets or pockets intermediate of the radially extending portions 7', which insure the proper placlng of the roller-bearings; intermediate member E is then placed on top of the cone or rollersions p, the upper surfaces 0 which 'lie in the same horizontal plane and thus provide a bearing surface for member A the outer circumferential rib or extension of course being formed slightly in from the periphery of member E 'so as to permit the member totake under the rim-portions or shoulderso'n member B as before described. I

' It will be seen thatwith the upwardly and the ownwardly extending circumferential flange b, which takes about the flan eon member B, a completely inclosed bearing is produced, thus obviating any possibilit of dirt. or undesirable matter getting into t e bearing. Furthermore, it will be seen, that a bearing is produced wherein the rollers o r cones are securely locked in place 'to one of the members, so that, there is less likelihood. of the rollers or cones becoming lost or jolted out of place during any unusual treatment of the bearin but instead,

aside from the possible pul ing away of member A, the bearing will remain in its assembled. condition by reason of the inter mediate member also acting as a locking means for the cones or rollers. It is ap parent that when member A is moved it will bear upon the extensions or ribs of member E, compelling this member to turn,

and when the positive or tooth and rack connection between intermediate member or locking means E and the roller-bearings is employed, the latter are compelled to turn.

In Figs. 8 and 9 I have illustrated one style of modification of my improved center'- earing, wherein the teeth on the cone-bearings D and the annular racks on members B and E are omitted. The construction in described.

other respects is identical to that heretofore The advantages of my improved bearing are readily apparent; and it is also evident that the construction shown and described may be varied in a number of details without departing from the spirit of my invenper and a lower mem o'rt ion or flange on member B tion, and I do not. wish to be understood therefore as limiting myself to the exact construction shown and described, but
